The Warnock Hersey Mark (WH)

The Warnock Hersey Mark (WH) is North America’s leading product safety and performance mark for building and construction products. 

Products bearing the WH Mark indicate compliance to relevant building codes, association criteria, and product safety and performance standards. Nearly 80% of North America’s wood fire-rated doors bear the WH Mark.

Fortress Door Company sells fire rated doors with 90, 60, 45 and 20 minute ratings
